Abstract
A motor vehicle includes a cab unit (3) tiltable relative to a vehicle frame (2) between a lowered state and a raised state. A first circuit (10) on the vehicle frame circulates a first medium. A second circuit (20) in the cab unit circulates a second medium. A heat transfer arrangement (4) transfers heat between the media. The arrangement includes a first heat transfer unit (11) on the vehicle frame, and in the first circuit and the first medium flows through it, and a second heat transfer unit (21) on the cab unit and in the second circuit and the second medium flows through it. These heat transfer units (11, 21) are in heat-transferring contact when the cab unit is in the lowered state and are separated when the cab unit is in the raised state.
Claims16
A motor vehicle with a heat transfer arrangement:
- the vehicle comprising:
- a vehicle frame;
- a cab unit which comprises a driver space, a separable connection between the cab unit and the vehicle frame such that the cab unit may be separated away from or moved to the vehicle frame;
- a first circuit configured for circulation of a first medium and situated at the vehicle frame;
- a second circuit configured for circulation of a second medium and situated at the cab unit;
- the heat transfer arrangement configured and operable for transfer of heat between the first and second media;
- the heat transfer arrangement comprising:
- a first heat transfer unit at the vehicle frame, facing towards the cab unit and incorporated in the first circuit to have the first medium flowing through the first heat transfer unit;
- a second heat transfer unit at the cab unit, facing toward the vehicle frame and incorporated in the second circuit to have the second medium flowing through the second heat transfer unit;
- and
- the first and second heat transfer units being located and respectively positioned as to be in heat-transferring contact with one another when the cab unit is moved to the frame and to be separated from one another when the cab unit is separated from the frame.
